While I've got the transmission out, it was recommended to go ahead and pull clutch/pressure plate & flywheel (some of my bolts were weeping oil).

Doing so, I reviewed the bits I "should" order (TO bearing, pilot bearing) for reassembly and I got to looking at the clutch material.

 

Sprung 4-puck ACT

 

I have 1-2mm worth of thickness before the rivets come into contact with metal spinning bits.

And yes, I do drive it on/off the trailer with a lot of slippage.

 

Time for a replacement clutch disk?

 

Next question: in replacing just the friction material, if there are no obvious marks on either the flywheel or PP, should those be resurfaced/trued before reassembly?

 

Thanks!

Doing some more digging on ACT's website, it appears to be a 4224205 disk and it's ceramic though I'm not finding a starting thickness listed there.

With it being a non-organic/metallic material, I think my concern about its usable life is unwarranted.

 

Any other thoughts from the peanut gallery?

I have never seen a ACT clutch wear out. Chip the corners off, yes. Slip due to oil soak, yes. But never wear out. And there is virtually no thickness between the friction surface and the rivets.

 

You should be OK

1-2 mm is about where they start.

Thanks for the vote of confidence in the clutch guys...

I think they have specs for minimal thickness somewhere on their site.  They have specs for minimal thickness.  I couldn't find it either last time I looked and called their support line to get the spec.

0.3 mm/0.012" measured from top of rivet head to clutch face.

 

I agree with others that the sintered metal puck clutches essentially never "wear" - if you have a flywheel flatness problem and/or have oil-soaking and/or are a voracious "slipper", you can get chipping due to heat.

+1 on thickness being OK as described.

When I received mine (4 pucks unsprung) when building my car, I was shocked as to how little material there was.
